FLUIDI ooN'rAINEn Joseph w. Patterson, Tulsa, Okla. Application October 21, 1940, Serial No.` 362,070 4 claims; (c1. 22o-27) This invention relates to new and useful improvements in fluid containers.

One object of the invention is to provide an improved container which is so constructed that a dispenser may be readily connected thereto, whereby the container may be marketed separately of and apart from the dispenser.

An important object of the invention is to provide an improved fluid container which is tamper-proof and which may be attached to the conventional uid sprayer barrel, or other dispensing apparatus, whereby the container .in which the fluid is sold may be utilized as the fluid container of the sprayer or other dispensing apparatus.

Another object of the invention is to provide an improved container, of the character described, wherein the means for connecting the dispenser to the container is disposed within the body of said container, whereby the exterior of the container is substantially smooth and also whereby said containermay be lled and sealed with the automaticequipment in general luse at the present time.

A particular object of the invention is to provide an improved container having an opening which is normally sealed by a frangible closure so that the container reaches the consumer in a sealed condition, the frangible closure being arranged to be ruptured when the dispenser is connected therewith so as to permit access to the contents of said container; the container being preferably constructed of a relatively inexpensive material so that it may be discarded after its contents are consumed and a new. full container substituted for the same, thereby obviating the necessity of employing a single receptacle with the dispenser and relling such receptacle from time to time.

A further object of the invention is to provide an improved non-rellable container having a positive seal at the point of its connection with a dispenser, whereby the container may only be used until emptied so'as to assure a new seal which substantially eliminates leakage.

Still another object of the invention is to provide a iiuid container, of the character described, wherein the contour of the container is utilized to co-actwith the connecting means between the dispenser and container so as to assure a tight connection therebetween.

A still further object of the invention is to provide an improved container wherein the sealing means is so arranged that any pressure within the container, when the container is attached to the dispenser, will tend to increase the seal between the parts to prevent anyleakage at the point of attachment.

A construction designed to carry out the in- -vention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and

wherein:

Figure 1 is an isometric view of an improved container, constructed in accordance with the invention,

Figure 2 is a plan view of the container,

This application is filed a-s a continuation-in-` part of my co-pending application Serial No. 316,311, filed January 30, 1940.

In the drawings, the numeral I 0 designates cylindrical container, can or receptacle which is constructed of tin, or other suitable material.

The container is made in the usual manner and v includes a cylindrical wall II which is formed of one piece of material and which has circular end plates or disks I2 crimped, or otherwise secured thereto, as shown in Figure 2. The container may be of any desired shape so as to have the desired fluid content. An opening I3 is formed in the wall ll of the container, being preferably disposed centrally with respect to the end walls i2 and being substantially circular in shape. A pair of diametrically opposed recesses I4 which are substantially semi-circular in shape, are provided at the marginal portion of the opening, and these recesses are disposed in a plane parallel to the tof the longitudinal axis shown) and recesses are curved, relative to a horizontal plane, as is clearly shown in Figure 3. However, since the recesses are disposed in alinement with the longitudinal axis of the container, and being of a narrower width than the circular opening, said recesses do not have as much curvature transversely thereof as does the opening. Due to the size of the openings, the transverse or lateral portion-s I5 of the opening, which are located in a plane at a right angle to the longitudinal axis of the container are disposed below the central portion of the openings in a horizontal plane as shown in Figure 3.

A cylindrical body or member I 6 which has the form of an inverted cap, is located within the container below the opening I3, and this member includes a base plate, or bottom I'I, provided with its upstanding angular flange I8. The upper end of the ange I8 is soldered, or otherwise secured, to the inside wall of the container immediately beneath said lopening and the diameter of said member is suicient to encircle the recesses I4, as well as the opening (Figure 4). The bottom I'I of the member is provided with an axial opening I9 which is normally sealed by a frangible closure disk 28. Since the bottom of the member It is spaced lfrom the opening I3, and also from the inner wall of the container, van internal chamber A is formed below the opening. An annular sealing gasket, or ring `2`I, maybe placed within this chamber, said gasket being positioned within the member' I6 prior to its attachment to the container. However, in some instances, Ythe gasket may not be necessary and may be omitted.

The member I6, as well as the opening 'I3 yand recesses I4, are `utilized to` connect the container, `or can Ill to a sprayer barrel,=or other dispensing apparatus, as will 'be hereinafter fully explained. It is pointediout that the member -Il is disposed within the container and 'takes 'up a relatively small amount of the internal area thereof, whereby it does not materially reduce the fluid content of said container. .'By `disposing the member within the interior :of ithe container, the outer surface thereof remainssmooth and no projections areformedxon such-surface. Therefore, the container has .an exterior construction which is exactly the same as the'usual containers or cans :which .arenow in general'use for marketingmotor oils, canned foods, and 'similar products,:and such containers Ymay Ybe .lilled and sealed with the present kind of automatic jelly'andsealing equip- -ment which isinow-in use. llt is specicallynoted Ithat no 'expensive `or special vequipment is required. The container may-be filled with an'in- -secticide or other iluid' to be sprayed or dispensed.

Theparticular type of containenor can, illustrated, Vis adapted to be connected to the depend- 'ngcollar r22 cfa sprayerbarrel (not'shown) whichalso includes a d-epending'eduction tube 123. -Aszis clearly-shown irrFigurei; the lower end fof the tubeprojects a substantialI distance below kthecollarf22. The diameter of thecollar4 is ysub- .-stantia-lly equalito the dialnet/er of the circular openingl` formed in thewallof the container I0, whereby thiscollar isinsertable therein. vA .pair of 'diametrically -opposed radially 4extending .ugs-2.4 arel Preferably formed'integral with the collar, and. said lugs extend ina plane parallel of the-sprayer barrel (not In-:attaching the sprayer barrel to the container,

t0 employ the lower end of the eduction tube 23 for this purpose. The tube is then introduced through the punctured disk and is lowered until the collar 22 enters the opening I3 in the Wall II of the container. The collar 22 is then rotated to aline the radial lug 24 with the recesses I4 which are located at the marginal portion of the opening I3. Due to the disposition of these recesses, as Well as the location of the lugs 24, it is necessary to aline the longitudinal axis of the container with the longitudinal axis of the barrel (not shown) in order to bring the lugs into registration with the recesses. After the lugs are alined with the recesses, further downward movement of the collar 22 may continue until the lower end thereof `strikes the gasket 2 I within the chamber A. At this time, the upper surfaces of the lugs '245i are within the chamber immediately below the inner wall thereof. Upon rotation of the collar 22, the lugs 24 are moved out of alinement with the recesses I4 Vand are engaged with the inner wall of the container beneath the marginal portion surrounding the circular opening I3, as is clearly shown in Figure 4. Due ito the curved inner surface of the container co-acting with the straight lugs 24, a cam action is had which serves to draw the vcollar 22 into a tight engagement with the packing gasket 2 I. Also, a tight frictional engagement between the lugs and -container is set up, whereby the connection between these 'elements is positively maintained.

It is manifest that when the container and the `collar-of a sprayer barrel -vare connected, as above described, -a complete sprayer is had .and that any drainage of fluid from the barrel will pass -downwardly through the collar and -then iback inte said container. It is vno-ted that any pressure present, `or which is built up in the 'container will vact against the underside of the bottom Il Iof the imember =I6 so as to :urge said member upwardly and force the gasket 2I against the lower end of the collar 22, thereby assuring a fluid- 'tight seal between saidcollar and gasket. When the container is empty, it is discarded and a new Vone is substituted therefor. By providing this type of container, a liquid insecticide, or other fluid, may be sealed in a container `which is temper-proof, so as to be in the same condition when offered for -sale to the consumer. After purchase, the consumer'may readily attach the container to the `collar of a sprayer barrel, or

vother dispenser, and dispense the contents'as` desired. Thus, the Lsame container whiohdsl em- Jployedfor sellingthe iluidis utilizedasa recep- -tacie for the sprayer'or dispenser.

`Since each container has a sealing gasket in- `corporatedtherein,it is m-anifest that each time -a container-is emptied, and a new one substituted therefor, a new seal is provided. This arrangement assures afluid-tight seal at the point of connection at' all times.

"ment is constructedfof an outerflange member 2 which is insertablewithin the opening 25, being `soldered or otherwise secured therein. The memlber 2? is comparableto the member I6, being provided with an axialv opening '23 which is closed .bya frangible 'disk 29. rIhe gasket 2 Ii is supported within the member and a flange -cap 3i] is also .'insertable Within the l member. `The top of the cap 30 is arced or curved so as to form a continuation of the curved surface of the container. The circular opening I3 and recesses I4 are provided in the curved top of the cap 30, and, manifestly, the collar 22 of the sprayer barrel or other dispenser may be readily connected thereto in the manner hereinbefore described.

Another form of the invention is shown in Figure 6 and includes a ange cap 3| which is secured in the opening 25. The top of the cap 3| is curved and is provided with the opening I3 and recesses I4, whereby said cap top forms a continuation of the wall I I and, in effect, a part thereof. The flange 32 of the cap depends into the interior of the container and has a circular base plate 33 extending across the lower portion thereof. The base plate has an axial opening 34 and this opening is normally closed by a frangible plate, or disk, 35 which overlies the plate 33. To simplify manufacturing costs, the marginal edges of the plates 33 and 35, as well as the ends of the flange 32, are crimped together. Of course, these points may be secured in any other suitable manner. Since the plate 35 is constructed of frangible material, such as lead or the like, it is not necessary that a sealing gasket be employed in this form. However, if desired, the gasket 2| may lbe used. Manifestly, the operation of this modification is the 'same as the other forms of the invention hereinbefore described.

In some instances, it might be desirable to construct a container in the manner shown in Figures 7 to 9. In this event, the wall of the container I is provided with an oval shaped opening 35 which is normally sealed by a frangible disk 3'I secured to the inner wall of the container beneath the opening. The sprayer barrel (not shown), or other dispensing apparatus, is provided with a depending collar 38 having lugs 39 thereon, and said lugs and collar are insertable through the opening 36, as will be readily understood. An annular flange 40 is formed on the collar above the lugs and, when said lugs are rotated to engage the underside of the container as shown in Figure 9, the iiange is spaced from the outer surface of said container. A suitable packing gasket 4I surrounds the collar l38 and is clamped between the outer surface of the container and the ange 40 so as to seal the opening 36. It is obvious that this is a relatively simple form of the invention and is preferably employed with sprayers and other dispensers which are not of the pressure type. However, it might be possible to clamp the gasket 4| suiiciently tight beneath the flange 40 to resist a leakage of pressure within the container. If desired, the frangilble disk 31 which seals the opening 36 may be secured to the external surface of the wall I i of the container as shown in Figure 10. It is pointed out that the openings of the containers which have been described hereinbefore may be formed in the circular end plates I2 of said container.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape, and materials, as wellas in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.

What I claim and desire to secure by Letters Patent is:

l. A dispensing container including, a container body having an opening in one of its walls, and a hollow member insertable within the opening and adapted to be fastened therein with its top substantially iiush with the outer surface of the container, the fbottom of the member having a frangibly-sealed outlet opening therein, the top of said member having an opening therein of a configuration to pass the fastening means of an element therethrough, whereby the container may be connected to the element by engagement of said. fastening means with the internal surface of the member contiguous to the opening thereof.

2. A container as set forth in claim 1, wherein a frangible disk normally seals the outlet opening formed in the bottom of the hollow member and the opening in the top of said member is substantially in the form of a slot.

3. A container including, a container body having an opening in one of its walls, a hollow member insertable within the opening and adapted to be fastened to the container with its top in said opening and substantially ush with the exterior surface of said container, the hollow member including a cap and a Ibase plate having an opening therein, the cap and base plate being secured together to form a unit, the top of said cap having a slot therein for receiving the fastening means `of an element, and a frangible plate closing the opening of said base plate. i

4. A container as set forth in claim 3 wherein the frangible plate is secured to the cap-and base plate of the hollow member.
